Cannot Share on Wireless Network with Win XP

I'm having a strange sharing problem and would appreciate any help: I just setup a wireless network with a USR router and 2 machines. 1 desktop machine has XP Pro installed on it and 1 notebook machine has XP Home installed. There is a printer attached to the desktop machine, and I'm trying to share it (and folders) with the other machine. I can see both machines in the workgroup, I can see the shares (and printer share), but when I try to connect to the printer i get a "Windows cannot connect to the printer. Operation could not be completed message". I can do a net print command and see the queue...I can even do a command line print that makes the printer respond for a second, but doesn't print anything. When I view the SharedDocs share, I can see all files/folders underneath, but when I try to open or copy a file it cranks for a while, then gives me an error. I don't have any firewalls on, I have both Guest accounts activated, I have NetBios over TCP/IP enabled on both machines, I have matching usernames/passwords on each machine, I have everyone added to the permissions on the printer share. The file share problem happens the same both ways (from 1 computer to another). Thanks...

 

Well, I've narrowed down the problem, so I posted a new thread. see:
